This dissertation describes research on chromium complexes with formally neutral, chelating ligands. The goal of this research is the fundamental study of organochromium chemistry with the hope of preparing Cr(II) complexes that are active for the polymerization or oligomerization of ethylene. This would provide evidence for Cr(II) to be active for these processes. Chapter 1 of this dissertation describes the synthesis and characterization of a series of chromium complexes supported by a chelating N-heterocyclic carbene ligand. The second chapter details the preparation and structural characterization of several complexes of chromium supported by several diimine ligands. The third chapter examines the organochromium chemistry derived from the complexes described in chapter 2. The final chapter entails the synthesis of the shortest metal-metal distance ever reported.

Organochromium Compounds is a three-chapter text that covers the major developments in the preparation, characterization, and reaction of the five main classes of organochromium compounds. These classes include the chromium p and solvated sodium and lithium poly(organo)chromate(III) and (II) complexes, carbenoid-chromium, solvated s-bonded organochromium(III) and (II), solvated sodium and lithium poly(organo)chromate(III) and (II) complexes, and unsolvated s-bonded tetra(organo)chromium(IV) compounds. This book will be of value to organic chemists and researchers who are interested in organotransition metal chemistry.

While this important reaction class is among the most important and most widely used in organic chemistry, this is the first book to summarize the many different olefination methods, including: * Wittig reaction * Peterson reaction * Julia olefination * Utilizing the Tebbe and related reagents * Low-valent chromium, zinc or titanium mediated olefination * McMurry coupling plus the related reactions in each case and the application to asymmetric synthesis. It thus collates in one ready reference the current level of knowledge as well as new developments in this constantly evolving field -- information which until now has been dispersed throughout the literature.

Recent advances in machine learning or artificial intelligence for vision and natural language processing that have enabled the development of new technologies such as personal assistants or self-driving cars have brought machine learning and artificial intelligence to the forefront of popular culture. The accumulation of these algorithmic advances along with the increasing availability of large data sets and readily available high performance computing has played an important role in bringing machine learning applications to such a wide range of disciplines. Given the emphasis in the chemical sciences on the relationship between structure and function, whether in biochemistry or in materials chemistry, adoption of machine learning by chemistsderivations where they are important

This volume is devoted entirely to inorganic and organometallic stereochemical subjects. Discusses the systematic notations that have been developed to satisfy the needs for a rational and systematic stereochemical nomenclature. Reviews the stereochemical aspects of the changes of bonding at carbon centers induced by metals, either catalytically or stoiciometrically. Also reviews the major achievements in current stereochemical research—the synthesis of asymmetric compounds mediated by transition metals. Discusses the structures of transition metal carbonyl clusters, summarizing recent progress in this expanding area and providing a semiquantitative rationalization of the structures for these clusters.

The biological activity of mycotoxins ranges from weak and/or sometimes positive effects, such as antibacterial activity (see penicillin derivatives derived from Penicillium strains) to strong mutagenic (e. g. aflatoxins, patulin), carcinogenic (e. g. aflatoxins), teratogenic, neurotoxic (e. g. ochratoxins), nephrotoxic (e. g. fumonisins, citrinin), hepatotoxic, and immunotoxic (e. g. ochratoxins, diketopiperazines) activity. Nowadays, many laboratories around the world are specialized in the detection of mycotoxins in food products and contaminated material found in housing. In this volume, a focus on the most important classes of mycotoxins is provided and their chemistry of the last ten years is discussed. In each Section, the individual biological impact is outlined. Sections are arranged according to mycotoxin classes (e. g. aflatoxins) and/or structural classes (e. g. resorcinyl lactones, diketopiperazines). The biology of mycotoxins is also described.

Since the discovery of ferrocene and the sandwich-type complexes, the development of organometallic chemistry took its course like an avalanche and became one of the scientific success stories of the second half of the twentieth century. Based on this development, the traditional boundaries between inorganic and organic chemistry gradually disappeared and a rebirth of the nowadays highly important field of homogeneous catalysis occurred. It is fair to say that despite the fact that the key discovery, which sparked it all off, was made more than 50 years ago, organometallic chemistry remains a young and lively discipline.

From boyhood in the coal-mining village of Coello, Illinois, to winning the Priestly Medal and becoming the president of the American Chemical Society, Professor Emeritus Fred Basolo of Northwestern University traces the intertwined development of his life, career, and the field of inorganic chemistry. With over a hundred photographs and dozens of structures and equations, From Coello to Inorganic Chemistry details the major innovations, travels, family life, and guests hosted while helping to build one of the world's leading inorganic chemistry departments from its humble beginnings at Northwestern University. Students and chemists with interests in bioinorganic chemistry, catalysis, nanoscience, new materials research, and organometallics can follow the emergence of inorganic chemistry as a rival to organic chemistry through the accomplishments of one of its most influential pioneers.
